VALVE FOR INTERNAL-COMBUSTION ENGINES.

Specification of Letters Patent.

Patented Mar. 10, 1914:.

To all whom it may concern Be it known that we, HARRY E. BAILEY and CLYDE PARSONS, citizens of the United States, residing at Green Castle, in the county of Sullivan and State of Missouri, have invented certain new and useful Improvements in Valves for Internal-Combustion Engines; and we do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention comprehends improvements in internal combustion engines of the four-cylinder type and relates more particularly to improved valves therefor.

The primary object of the invention resides in the provision of a sliding plate valve which operates within a casing secured'to the exterior of the cylinder, which is of extremely simple construction, cheap to manufacture, and very eiiicient.

Another and more specific object of the invention resides in the provision of a valve of this nature and means for lubricating the same.

With these and other objects in view, as will become more apparent as the description proceeds, the invention consists in certain novel features of construction, combination, and arrangement of parts, as will b hereinafter described and claimed.

For a complete understanding of the invention reference is to be had to the following description and accompanying drawings, in which,

Figure 1 is a longitudinal sectional view, partly in elevation, through, an engine equipped with our improved valve, Fig. 2 is a side elevation of an engine cylinder equipped with our improvedvalves, Fig. 3

1s a fragmentary sectional view taken on the lane of line 33 of Fig. 1, and, Fig. 4 1s a detail perspective view of one of the plate valves.

Referring in detail to the drawings by numerals, 5 designates a cylinder of a fourcycle englne havmg an intake port 6 and an exhaust port 7. A water jacket casing 8 surrounds the cylinder and ports, as clearly shown in Fig. 1. Valve casings, generally designated 9 and 10, are secured to opposite sides of the cylinder and cover the ports 6 and 7. Each of these casings comprises an outer wall 11, which extends in parallel re lation with respect to the outer surface of the cylinder, oppositely inclined side walls 12 having flanges 13 extending from their inner edges, and a top wall 14. Suitable fasteners 15 extend through the top wall 14 and the flanges 13 to secure the casings to the cylinder.

Plate valves 16 and 17 are adapted to reciprocate within the chambers formed by the valve casings, to open and close the ports 6 and 7. These valves are formed with the openings 18 which are adapted to register with the ports 6 and 7, respectively, have their upper ends inclined outwardly, as indicated at 19, their side walls inclined as indicated at 19, and are formed upon their lower ends with lugs 20, to which connectmg rods 21 are pivotally attached. The rods 21 are threaded into sockets formed in the upper ends of the bars 22, which bars are provided with rollers 23 adapted to be engaged by cams or other suitable actuating means, not shown. These bars slide through guide casings 24.

011 may be admitted to the tops of the chambers formed by the casings 9 and 10, by means of the pipes 25, which are provided with check valves 26, and pipes 27 are employed to lead the oil from above the valves to those portions of the chambers which are disposed below the ports 6 and 7. The plate valves are formed upon their inner faces adjacent their upper extremities with the downwardly and outwardly inclined oil grooves 28 and below the port 18 with the grooves 29. A transverseopening 30' extends through each of the plate valves and is for the purpose of conducting the oil from the front to the rear side thereof. If desired, the outer faces of the valves may also be grooved to insure a proper distribution of the oil over their entire surfaces.

The cylinder 5 is formed with outwardly facing recesses 29 in the water jacket casing 8 above and below the ports 6 and 7. These recesses extend across the valve chambers and receive packing strips 30 which are forced against the valves by means ofsuitable springs 31. These strips act as a partial seal to prevent the escape of compressed gases when the valves are closed by engaging the inner faces of the valves above and below the ports 6 and 7.

From the foregoing description taken in connection with the accompanying drawing, it will be seen that the valve may be properly operated by any-suitable means, so as to open and close the intake and exhaust ports in such a way as to insure an efiicient little power. Since they work upon the outside of the cylinder wall they are not exposed to the direct heat of the exploded gases, and therefore work more satisfactorily than would otherwise be the case.

The means which we have provided for lubricating the valves is.very simple and practical. As the valves move upwardly the oil, above them will be forced through the pipes 27 and will lubricate the lower portions of the same.

It is to be understood that while we have shown and described the preferred embodiment of ourinvention, we do not wish to be limited to this exact construction, combination, and arrangement of parts, but may make such changes as will falliwithin the spirit and scope of the invention.

Having thus described our invention, what we claim is 1. In combination with a cylinder having a port formed therein, a plate valve slidable upon the outer wall of the cylinder to open and close said port, a casing surrounding the valve and holding it in engagement with the cylinder, means for introducing oil into one end of the casing and a duct for conveyingoil from said end to a portion of the casing on the opposite side of the port.

2. The combination with a cylinder having a port formed in the wall thereof, of a sliding valve engaging the exterior of the cylinder to open and close said port, a casing surrounding the valve to hold it in engagement with the cylinder, the casing being closed at one end and formed with an opening in alinement with the port, means for introducing oil into the closed end of the casing and a duct adapted to convey oil from said closed end of the casing to a point on the opposite side of the port.

3. The combination with a cylinder having a port formed in the wall thereof, of a plate valve slidable upon the exterior of the cylinder to open and close the port, a casing fitted around the valve to hold the same in engagement with the cylinder, said casing being closed at one end, means for introducing oil into the closed end of the casing, and a duct communicating at one end of the closed end of the casing and at its other end with the casing at a point -on the opposite side of the port, the valve being formedwith oil receivlng grooves.

4. The combination with a cylinder having a port formed therein, of a plate valve slidable upon the exterior of the cylinder to open and close said port, a casing fitted around the valve to hold the same in engagement with the cylinder, one end of the casing l ing closed, means for introducing oil into said closed end the faces of the valve being formed with oil grooves and said valve being alsoformed with a transverse oil passage,'whereby oil may be conveyed from one side of the valve to the other, and a duct leading from the closed end of the casing to a point on the opposite side of the port, whereby oil will be conveyed across the ort so that both ends of the valve may be lu ricated.

In testimony whereof we afiix our signatures in presence of two witnesses.
